cisco several good-sized flocks of ducks passed us heading southeast. February 10, 1911. Alameda to San Francisco, california. Strong southeast wind; overcast; A.M.; rear deck steamer. Along the seawall and mole I saw several Larus glaucescens and Larus californicus flying eastward. A few ducks were seen on the water and four cor- morants flying northwest high in the air. On the piling at the mole there were several gulls and on one pile a cormorant. A lot of Larus glaucescens, immature, and several Larus californicus followed the steamer across sailing more than usual. Many gulls were sailing about like shearwaters with a big sail and rise and fall, flapping the wings on the upward swing and sailing on the downward, usually just skimming the water. Just as we entered the slip on the San Fran- cisco side I saw a fine adult Larus argentatus. February 11, 1911. Alameda to San Francisco, california. Cold; southerly wind; clear in morning; cloudy in afternoon. Off the seawall there was a scattering flock of thirty or so ducks which appeared to be mostly Edemia per- spicillata judging from the white patches on the backs of the heads. A few scattering ducks were seen along the mole, one of which was an Edemia deglandi.
